6304 ISB deep groove ball bearing

ISB 6304 Deep Groove Ball Bearing (Heavy-Duty Series)

The ISB 6304 is an open-type single-row deep groove ball bearing, engineered for high radial load capacities. As a member of the 6300 series, it provides significantly higher dynamic and static load ratings than 6200 series bearings with the same bore diameter. Featuring precision-ground raceways and high-grade bearing steel, this model ensures low friction torque and exceptional durability in industrial applications.

Application

• Gearboxes and Transmissions: Ideal for oil-bath operation where high load capacity is required.
• Electric Motors: Stable rotor support under significant radial forces.
• Pumps and Compressors: Resistance to dynamic loads in continuous duty cycles.
• Agricultural Machinery: Durable shaft support for farming implements and drives.
• Machine Spindles: Used in auxiliary systems requiring stable and accurate rotation.

Technical Specification

• Manufacturer: ISB (Italy)
• Designation: 6304
• Type: Single-row deep groove ball bearing
• Design: Open (no seals – requires external lubrication).
• Series: 6300 (Reinforced load capacity).

Note: Standard dimensions for the 6304 are 20 mm (Bore) × 52 mm (OD) × 15 mm (Width).

Features and Benefits

• Robust 6300 Architecture: Larger rolling elements support forces beyond the capability of light series bearings.
• Open Design: Allows for free lubricant flow (oil or grease) and efficient heat dissipation.
• High Speed Limits: ISB’s precision grinding ensures stable performance at high RPMs with low noise.
• Versatility: Capable of managing axial loads in both directions while maintaining superior radial capacity.
• Premium Quality: European quality control ensures long service life and extended maintenance intervals.

Why Choose This Product

The ISB 6304 bearing is a cornerstone of reliability for your mechanical systems. By choosing the 6300 series, you invest in a higher safety margin – this bearing withstands stress where standard models might fail prematurely. The manufacturing solidness of the ISB brand leads to real savings by reducing the frequency of failures and service downtime in your facility.
